This Orku 15L Digital Ultrasonic Jewelry Cleaner has a microprocessor-controlled device that uses ultrasonic or high-frequency sound waves to clean jewellery and other delicate items. The vibration of ultrasonic waves in the liquid will cause strong cavitation and emulsification. Millions of cavitation bubbles can be generated per second. Under the action of sound pressure, these bubbles are rapidly produced and continuously violently blasting, producing a strong impact and suction force to remove stubborn dirt and kill bacteria and viruses. Built-in powerful transducers can strengthen the ultrasonic power and produce a superior cleaning outcome. Utilise the digital programme to control the unit according to the quantity and condition of the items to be cleaned and to choose a working cycle time. As a result, it is more convenient and efficient than hand washing, steam cleaners, high-pressure water jet cleaning or other machines. Advanced brushed stainless steel 304 cleaning tank to avoid corrosion water stains and to keep the tank looking always new.
